“…It means that the crystal-melt interfacial free energy for CoSi and CoSi nuclei in the undercooled melt would play a decisive role in determining the primary nucleation phase. However, quantitative analysis for the primary phase selection with undercooling is challenging since the crystal-melt interfacial free energy of both phases is temperature-dependent and is a function of how the local structural similarity between the liquid and two phases changes with undercooling [27][28][29].…”

Solidification and growth behavior of undercooled eutectic CoSi-CoSi 2 melts was observed using containerless levitation and in situ high-energy synchrotron X-ray diffraction techniques. Three metastable solidification pathways of eutectic CoSi-CoSi 2 were determined as a function of undercooling. Upon double recalescence at low undercoolings the primary and secondary phases are CoSi and CoSi 2 , while at high undercoolings the phase formation sequence is reversed. At intermediate undercoolings a single recalescence was observed and attributed to a crossover of the nucleation barriers for the two phases. Scanning electron microscopy combined with electron back-scattering diffraction measurements revealed changes of the morphological characteristics and orientation of CoSi and CoSi 2 phases for different solidification pathways.

“…The mobility of molecules/atoms at the homogeneous solid-liquid (S-L) interfaces is a controlling factor in a number of technologically relevant fields, such as self-assembled monolayer growth and nucleation [1][2][3][4][5][6]. However, the mechanism of the liquid molecules/atoms moving on solid surfaces remains mysterious and a matter of debate.…”

“…Therefore, it is not straightforward to discuss the change in solid–liquid interfacial energy out of the equilibrium condition. Specifically, the temperature dependence of the solid–liquid interfacial energy is still under discussion [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ]. Several theoretical and computational studies have reported that the solid–liquid interface increased with increasing temperature (i.e., the positive temperature dependence) [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ], whereas other literature has indicated that the temperature dependence of solid–liquid interfacial energy was not monotonic [ 39 , 40 ].…”

Different temperature dependencies for the interfacial energy of an unstable equilibrium (i.e., for nuclei) have been theoretically predicted [ 41 ].…”

Bayesian Data Assimilation of Temperature Dependence of Solid–Liquid Interfacial Properties of Nickel

Temperature dependence of solid–liquid interfacial properties during crystal growth in nickel was investigated by ensemble Kalman filter (EnKF)-based data assimilation, in which the phase-field simulation was combined with atomic configurations of molecular dynamics (MD) simulation. Negative temperature dependence was found in the solid–liquid interfacial energy, the kinetic coefficient, and their anisotropy parameters from simultaneous estimation of four parameters. On the other hand, it is difficult to obtain a concrete value for the anisotropy parameter of solid–liquid interfacial energy since this factor is less influential for the MD simulation of crystal growth at high undercooling temperatures. The present study is significant in shedding light on the high potential of Bayesian data assimilation as a novel methodology of parameter estimation of practical materials an out of equilibrium condition.
